US Sen. Tom Cotton (R-AR) has called on the Federal Bureau of Investigation (FBI) to investigate a pro-Hamas activist who urged supporters to sabotage the US supply chain for the F-35 fighter jet, one of America’s most advanced military assets and a critical component of Israel’s defense.

In a letter sent to FBI Director Kash Patel on Wednesday, Cotton warned that Aisha Nizar, a leader and organizer of the Palestinian Youth Movement (PYM), “directly endangered US national security” when she addressed a Palestinian conference in Detroit last week. Durin the event, Nizar told attendees that targeting “nodes” in the F-35 production process could have “a huge impact” on the program.

“We need to be surgical. We need to be strategic … Because there are many different points of these supply chains of death that we can intervene in and we must intervene in,” Nizar said at the People’s Conference for Palestine.

The F-35 program is widely regarded as a cornerstone of US and allied air power, and Israel is the only country in the Middle East authorized to operate the jets. Cotton argued that calls to undermine the program represent not just anti-Israel activism, but also a direct assault on American workers and defense readiness.

“Nizar’s statements constitute direct incitement of violence against US national security interests by advocating for actions against the men and women who build the F-35,” Cotton wrote. He urged the FBI to “immediately examine Nizar’s actions and take any necessary actions to mitigate the threat.”

PYM has emerged as one of the most radical anti-Israel, pro-Hamas groups in the US since the war in Gaza started, organizing raucous protests targeting Jewish and pro-Israel events across the country.

Nizar has previously faced legal trouble over her role in disruptive protests amid the Israel-Hamas war, including a demonstration that shut down the Golden Gate Bridge in San Francisco. Cotton, an outspoken supporter of the US-Israel strategic alliance, said her ties to PYM, which he has accused of harboring antisemitic views and benefiting from questionable tax-exempt donations, warrant closer scrutiny.

“The defense supply chain is a key to our military’s ability to fight and win wars. We must protect that supply chain from all enemies, foreign and domestic,” he concluded in his letter.
